2 Claims.

This invention relates to a burner particularly adaptable to oil, acid sludge oils, and the like.

An object of my invention is to provide a novel burner, which is simple to assemble and take apart, and which can be easily cleaned and repaired when necessary.

A feature of my'invention is the novel adjustable separator between the steam and fuel supply pipes, which can be quickly and easily adjusted when necessary.

Another feature of my invention is the absence of threaded parts in the firebox, thereby providing a burner which is easy to assemble and which has no parts which will be corroded or burned and, therefore, difficult to remove.

An advantage of my novel oil burner is its durability under acid sludge operations or the use of other fuels.

A further advantage of my burner is the dual atomization accomplished by the expansion of the steam and also mechanically through a thin wall orifice.

A further object of my invention is the reduction of metal in the firebox, thus minimizing coking within the conductors.

Other objects, advantages and features of invention may appear from the accompanying drawing, the subjoined detailed description, and the appended claims.

In the drawing:

Figure 1 is a top plan view of my oil burner.

Figure 2 is a side elevation of the same.

Figure 3 is a fragmentary, transverse sectional view of the outer end of the body.

Figure 4 is an end view of the body.

Figure 5 is a fragmentary, side elevation of the outer end of one of the conductors.

Figure 6 is a fragmentary elevation taken at right angles to Figure 5 of one of the conductors. Referring more particularly to the drawing, the numeral l indicates an elongated body or housing, provided with an opening or bore extending from end to end of the body. The inner wall 2 of this body is tapered towards one end, the purpose of which will be further described. A pair of conduits 3 and 4 extend through the body I and project beyond the end of the body substantially as shown in Figures 1 and 2. The body I is provided with arcuate seats 5 and 6 at the outer end, in which the conduits 3 and 4 rest, and which assist in holding and also guiding the conduits to their proper position. The conduits also rest against the inner tapered walls 2 so that the ends of the conduits are pressed together, thus a thin wall orifice is provided, through which the oil and steam escape into the firebox. The ends of the conduits 3 and 4 are each flattened or machined as shown at 'l to provide a bearing surface, and also to prevent accidental rotation of the conduits. The conduits are also cut away at their tips, as shown at 8, and the opening from each of the conduits is thus arranged so that the streams of fuel oil from each conduit impinge upon each other. Set screws 9 and I0 extend through the body and bear against the conduits 3 and 4 respectively, thus holding the conduits securely in position.

To effectively separate the ends of the conduits 3 and 4, I provide a flat plate H, which extends longitudinally through the body and is positioned between the inner tips of the conduits 3 and 4. The plate I l protrudes slightly beyond the inner ends of the conduits 3 and 4, and the cut out or recessed portions 8 of the conduits form with this plate a thin wall orifice, through which the steam and fuel escape into the firebox. A set screw l2 extends through the body I and bears against the plate ll, thus holding this plate against displacement.

It will be apparent that the conduits 3 and 4 are wedged tightly against the plate H due to their convergence and mounting in the body I. To take the burner apart, it is merely necessary to release the set screws 9, l0 and I2, and thereafter the conduits 3 and 4 and the plate H can be easily removed from the body for cleaning or replacement purposes. If the inner end of the plate ll burns off, it'is only necessary to loosen the set screw l2 and move the plate ll inwardly to its proper position. The conduits 3 and 4 are open from end to end and, therefore, can be easily cleaned of any coke or other accumulation. Similarly, the inner ends of these conduits as well as the plate H can also be easily cleaned.

A portion of the body I and the inner ends of the conduits 3 and 4 are all that project into the firebox, andconsequently there are no delicate or threaded parts which are exposed to the heat or flame. The outer ends of the conduits?! and 4 are threaded to receive a suitable coupling on the conduits, which carry steam and oil to the respective conduits. Due to the arcuate opening at the inner end of each of the conduits 3 and 4 and the impingement of the steam and oil against the separator plate H, an effective atomization and mixing of the oil is obtained, thus producing a hot flame and a reduction in the amount of fuel consumed.

Having described my invention, I claim:

1. An oil burner comprising a pair of conduits,

a body in which the conduits are mounted, one of said conduits carrying oil, and the other conduit carrying steam, a plate mounted in the body, said plate extending between the conduits and the one end of each of said conduits bearing against the plate, means in the body holding said conduits in position with the said ends pressed against the plate, said conduits having an opening at the said ends thereof directed towards the plate, and releasable means in the body engaging the plate, said plate being adjustable longitudinally in the body.

2. An oil burner comprising a body, said body having a pair of seats formed therein, and extending longitudinally thereof, said seats conver ing towards one end of the body, a pipe seated in each of said seats, a plate mounted in the body and extending between the pipes, the discharge end of each of the pipes bearing against the plate, each of the pipes having an opening at the discharge end bearing against said plate, said opening being directed towards the plate, said plate being adjustable longitudinally in the body, and means in the body engaging the plate and holding the same in adjusted position.
